A computer virus is a harmful program that is developed by people who wish to cause harm or disruption to systems and computers. They are hidden bits of code that ride a ride on other programs or applications and when activated they spread like wildfire. Viruses are usually found attached to documents or programs that were downloaded from the Internet or distributed via email. The majority of countries think that the creation and spread of computer viruses is illegal.
There are a variety of computer viruses that are able to attack computers in a variety of ways. Some depend on a program to start their work and others are self-contained and can infect multiple systems without the need of the host. A computer virus that utilizes host programs to attack computers is often considered as a worm but those that don’t make use of the method used to infect through other programs are deemed to be viruses.
Certain viruses are able to begin infecting systems as soon as they arrive, whereas other remain dormant until the user accidentally executes the code. The first computer virus was developed in 1974, and it acted as a biological virus by multiplying itself rapidly and causing harm to the system. Stuxnet is an example of a destructive computer virus. It was created to destroy computerized centrifuges which were used to enrich the uranium content.
The process of creating a virus can be very complicated and isn’t for the faint of heart. However it can be an enjoyable and interesting method of testing your proficiency in computer programming languages and systems. There are a lot of resources that can show you how to create a virus, if you are willing and able to put in the effort.
